You can use the below code in your observer to add order comment:

$comment = "Comment to be added in the order";

Or you can use below free extension you can use for adding order comments on the checkout page.



Check the code below for simple add customer comment to order via observer:

// get the last order
$lastOrderId = $this->_getOnepage()->getCheckout()->getLastOrderId();
$order = Mage::getModel('sales/order')->load($lastOrderId);

// Add the comment and save the order (last parameter will determine if comment will be sent to customer)
$order->addStatusHistoryComment('This comment is programatically added to last order in this Magento setup');
